February 2, 2021
I’m reliably informed that the 2021 edition of the Arcati Mainframe Yearbook has now been published. This fascinating publication is completely free and can be downloaded from the Arcati website.

2020 must have been the year that no-one expected in the early hours January 1 as they celebrated its arrival. According to the Collins Dictionary, the word “lockdown” had a 6,000% increase in usage since 2019. The other pandemic-related words on the dictionary’s list of the top 10 words for 2020 were: “coronavirus,” “social distancing,” […]
